I follows all the steps in a Sony VAIO PCG-GRX707. I stop in the point that as I have 2 logical units (C: y D: <-factory restore). So, I have a USB External Hard Disk with sufficient space.
I runned everything again: I didn't use fb800, and linux found the hard disk. But, at this time I haven't backup my data.
What do you think about to install Ubuntu in a USB Hard disk follow the exact steps, could be this possible?
Give me a week and I'll try it. But I'd to hear comments. Thanks!.
